Table 628 Meanings of characters in text

Character Meaning Remarks

+	Addition, used to match a
	subexpression before it one or
	multiple times

zo+ can map to “zo” and “zoo”, but not “z”.

-	Hyphen. It connects two values (the
	smaller one before it and the bigger
	one after it) to indicate a range
	together with [ ].

For example, “1-9” means numbers from 1 to 9 (inclusive); “a-h” means from a to h (inclusive).

[ ]	Selects one character from the
	group.

For example, [1-36A] can match only one character among 1, 2, 3, 6, and A.

( )	A group of characters. It is usually
	used with “+” or “*”.

For example, (123A) means a string “123A”; “408(12)+” can match 40812 or 408121212. But it cannot match 408. That is, “12” can appear continuously and it must at least appear once.

Description Use the display logbuffer command to display the state of the log buffer and the log information recorded. Absence of the size buffersize argument indicates that all log information recorded in the log buffer is displayed.
